IMPROVEMENT IN CHECK-ROW ATTACHMENTS FOR CORN-PLANTERS.

Specification forming part of Letters Patent No. 173,650, dated Februarv 15, 1876; application filed December 5, 17874.

[o all whom it 'may concern:

vin which like letters ot' reference refer to like parts, and in Which- Figure l represents a plan view of cornplanter and check-row-attachment in operaf tion; Fig. 2, a view of the under side of the revolving plate E Fig. 3, a rear elevation of check-row attachment; Fig. 4, a vertical sec` tion of same -along dotted line b b, b b, Fig. 1, as to Wheel and platform only; Fig. 5, a vertical cross-section on line a c, a a, Fig. 1.

This invention consist-sof a horizontal revolving cam-plate, having a notch at each corner to receive the knotted rope, and attached on one side-of the machine, in combination with a guide and pivotal lever arranged to connect with the cut-off` bar, the Whole constructed and arranged to mark the rows for the corn, as will loe hereinafter more fully expained.

vIn the drawings, A A represent the seedboxes; H, their lower connectingbar, and lc, the upper one, upon which this attachment is seated at the outer end. It consists of a horizontal platform, D, having a guide, h, on a level with the surface, perforated in a line parallel with the runners m and with the cord F, for the passage of the latter through it with its knots, and a curved guard or wall, t', on its outer edge, to hold the cord within the notches of the armsfof the wheel E. In a recess on said platform D is pivoted the short lever C, (at 11,) having a short vertical pin,d, on the surface of its shorter arm, beneath the wheel E, and which works within the gure-8-shaped groove g on the under side of said wheel. The Wheel E is pivoted, at e, in a line with pin d, and the connecting-bar H k, and (besides said groove g) is provided with four or more arms, notched at the pointsfto admit the rope F as the machine advances parallel therewith, the knots of which, striking the arms f, rotate said wheel E, which thus oscillates the lever C, rod b, lever a, and cut-off bar B of the seedboXes.

What I claim as my invention is- The horizontal revolving cam-plate E, having notched corners f to receive vthe knotted rope F attached to plateI) on one side of the machine, in combination with the guide h, guard t', pivotal lever C, rod b, pivotal lever c, and

seed-slide B, constructed and arranged to operate in the manner and for the purposes set forth.

In testimony that I claim the foregoing v
